"Power, especially overgrown power, whets the ambition and sets all the wits to work to enlarge it. Therefore, encroachments on peoples liberties are not generally made all at once, but so gradually as hardly to be perceived by the less watchful; and all plastered over, it may be, with such plausible pretenses, that before they are aware of the snare, they are taken and can not disentangle themselves."

I used a ADC street map in plotting my yards out when setting a breeding program. The area maps are large enough with detail that 5-1/4 inch made a 2 mile circle. It not only allowed me to concentrate on finding farms within a certain distance, but kept the distance in an area good for drone yards and genetic saturation.
